York County, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Karinna Nunez, Sharon Killeen, Tamia Rudnicky, Carl Hershner, Kory Angstadt, David Stanhope, David Weiss, Karen Duhring, Christine Tombleson

Reports

The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions: 1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.

2012 Chesapeake Bay Sav Coverage, Sav Data Administrator, Virginia Institute Of Marine Science

Data

Abstract: The 2012 Chesapeake Bay SAV Coverage was mapped from 1:24,000 black and white aerial photography to assess water quality in the Bay. Each area of SAV was interpreted from the rectified photography and classified into one of four density classes by the percentage of cover. The SAV beds were entered into an SDE GIS fetaure class using the quality control procedures documented below. The dataset contains all SAV areas that were identified from the areas flown. Some areas that are presumed to contain no SAV were not flown. Some small beds, particularly along narrow tributaries may not have been …

Reports

The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. In most cases this assessment characterizes conditions that can be observed from a small boat navigating along the shoreline. The three tiered shoreline assessment approach divides the shorezone into three regions:

1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes. GPS registered videography was used to collect data on conditions observed in the field.

Development Of A Coastal Resources Certificate Program For Marine Contractors & Consultants, Karen Duhring, Julie Bradshaw

Reports

The Center for Coastal Resources Management at VIMS has been engaged with continuing education and training for a mixed audience over the past 35 years. Marine contractors and consultants play an important role in the evolving field of tidal shoreline management. This Creative Adaptation Fund project investigated the unique training needs of this private sector audience and attempted to define the best format and delivery for a Coastal Resources Certificate Program. It was determined that training needs for shoreline professionals can be met with a multi‐day short course that includes both classroom and field settings. This private sector audience expressed …

Dune Monitoring Data Update Summary: 2013, Donna A. Milligan, C. Scott Hardaway Jr., George R. Thomas

Reports

The Shoreline Studies Program at VIMS established a beach and dune monitoring program for nine sites around the Virginia portion of Chesapeake Bay (Milligan et al., 2005). These sites were monitored twice yearly for four years (2001-2004). In addition to three years of relatively calm conditions, these data included the impact of Hurricane Isabel, a nearly 100-yr event, on the Bay’s shorelines. The shoreline’s change due to the storm and their subsequent short-term recovery was documented by this data. Since the end of the monitoring program other events have impacted Chesapeake Bay shorelines. In order to document the longer-term recovery …

VIMS Articles

The extent, duration, and seasonality of sea ice and glacial discharge strongly influence Antarctic marine ecosystems. Most organisms' life cycles in this region are attuned to ice seasonality The annual retreat and melting of sea ice in the austral spring stratifies the upper ocean, triggering large phytoplankton blooms. The magnitude of the blooms is proportional to the winter extent of ice cover, which can act as a barrier to wind mixing. Antarctic krill, one of the most abundant metazoan populations on Earth, consume phytoplankton blooms dominated by large diatoms. Krill, in turn, support a large biomass of predators, including penguins, …

Shoreline Evolution: Northampton County, Virginia Chesapeake Bay Shoreline 2013, Donna A. Milligan, Christine A. Wilcox, C. Scott Hardaway Jr.

Reports

Northampton County is situated along Virginia’s Eastern Shore (Figure 1). Because the County’s shoreline is continually changing, determining where the shoreline was in the past, how far and how fast it is moving, and what factors drive shoreline change will help define the shoreline’s future movement. These rates and patterns of shore change along Chesapeake Bay’s estuarine shores will differ through time as winds, waves, tides and currents shape and modify coastlines by eroding, transporting and depositing sediments. The purpose of this report is to document how the Chesapeake Bay shoreline of Northampton County has evolved since 1938. Aerial imagery …

Monitoring Relative Abundance Of American Shad In Virginia Rivers 2012 Annual Report, Eric J. Hilton, Rob Latour, Brian Watkins, Ashleigh Magee

Reports

Concern about the decline in landings of American shad (Alosa sapidissima) along the Atlantic coast prompted the development of an interstate fisheries management plan (FMP) under the auspices of the Atlantic States Marine Fisheries Management Program (ASMFC 1999). Legislation enables imposition of federal sanctions on fishing in those states that fail to comply with the FMP. To be in compliance, coastal states are required to implement and maintain fishery-dependent and fishery-independent monitoring programs as specified by the FMP. For Virginia, these requirements include spawning stock assessments, the collection of biological data on the spawning run (e.g., age-structure, sex ratio, and …

Lynnhaven River Shoreline Management Plan, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox, Mary C. Cox, Marcia Berman, Tamia Rudnicky, Karinna Nunez, Sharon Killeen

Reports

The shores of Lynnhaven River are fairly sheltered coasts. In addition, much of the shoreline has existing hardened shore protection. However, much of Lynnhaven River’s shoreline is suitable for a “Living Shoreline” approach to shore-line management. The Commonwealth of Virginia has adopted policy stating that Living Shorelines are the preferred alternative for erosion control along tidal waters in Virginia (http://leg1.state.va.us/cgi-bin/legp504.exe?111+ful+CHAP0885+pdf). The policy defines a Living Shoreline as …”a shoreline management practice that provides erosion control and water quality benefits; protects, restores or enhances natural shoreline habitat; and
maintains coastal processes through the strategic placement of plants, stone, sand …

Rehoboth Bay, Delaware Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Sharon Killeen, Carl Hershner, Karinna Nunez, Karen Reay, Kory Angstadt, Tamia Rudnicky, Dan Schatt, David Stanhope

Reports

Shoreline Situation Reports (SSR) were first generated by VIMS in the 1970's to report the condition and status of the shore lands. The SSR series were published in hardcopy on a county by county basis for each of the Tidewater Virginia localities. The reports were intended to assist planners, managers, and regulators in decisions pertaining to management of coastal areas and natural resources therein. This is the first Shoreline Inventory Report for the Rehoboth Bay section of Delaware. Data collected describes conditions in the immediate riparian zone, the bank, and along the shore. There are three shapefiles that are part …
